David James Lunz, 56, was murdered in his Palm Harbor, Florida, home sometime between the evening of March 6 and the morning of March 7, 2003. Neighbors reported newspapers piling up and requested a welfare check; officers found Lunz near his bedroom with severe head trauma and blood pooling around him. The scene showed signs of a violent struggle that began in the living room and ended in the bedroom, and two glasses on the living room table suggested he had been expecting company. Substantial cash was left in the house, so robbery was not the apparent motive.

Investigators later identified Lunz’s estranged son, Christopher Lunz, and an accomplice, William Timothy Eugene Westerman, as suspects. The account states Christopher struck his father with the butt of a sawed-off shotgun and Westerman shot him at point-blank range; several items were stolen, including a Smith & Wesson .38/.44 revolver and a gold Fendi watch. A revolver recovered from the bank of Cedar Cliff Lake in 2005 tied Westerman to the case; he confessed and implicated Christopher. Christopher was arrested and convicted; Westerman was sentenced to 30 years for second-degree murder.

Did anyone in the community know of tensions between David Lunz and his son that might shed light on what led to this visit?
